StoreKit In App Purchase invalid product identifiers [duplicate]

Answer 1

After struggling for a day or so with invalid products being returned, my solution came down to making sure the purchase item was "Developer approved for sale". Even though there was a green mark next to the item saying "cleared for sale", I still needed to upload a screenshot and select approve.

This seems like a backwards and illogical way of doing things considering I'm still testing my app and not yet ready to put it on sale.

Answer 2

I tried everything suggested in the Apple forums and here, and still couldn't get it to work.

Found the solution:

Your app needs to be transferred by Xcode for the sandbox to be enabled.

Your app needs to be built and installed locally by Xcode, not downloaded from the App Store.

Obvious, right? Well, if you are working with an update to an existing application, the device will still treat it as an App Store-installed app.

So delete the app from your device. Then install the app back onto the device using Build & Run with your device tethered to your Mac. It should work now :)

Answer 3

I have 15 non-consummable products.

Suddenly, all 15 of them started to appear as 'invalid' in one of my devices (iPod Touch 4G), but valid in the other (iPhone 4S); very weird indeed.

I deleted/reinstalled and now it works OK.

Someone said you must launch from Xcode, but this is not necessarily true. I have many beta testers with AdHoc builds and Test User accounts, and most of the time they seem to be able to purchase OK.

That said, the whole Sandbox Environment is always shaky and has plenty of "down time". Sometimes waiting is the answer.

Answer 4

I'm one the the victims here. Well, I was. Yesterday, I had the problem and revised a lot of times all the steps. Today, I reviewed all the list from troybrant.

1. ok my mistake, I forgot to create the proper distribution profile:fixed

2. uploaded a binary and rejected immediately: they say it works better than no uploading

3. ok, other fix: removed the 10 digits before my domain name from everywhere in Xcode (XXXXXXXXXX.com.company.app to com.company.app)

Still not working.

4. Check my device not to be connected with an iTunes account.

5. Clean build every time and remove app from device sometimes

Still not working.

6. Finally, when asking for products, I used only the productID, not the whole com.company.app.productID.

AND it worked.

I think sometimes we have more than 1 mistakes, and when you correct all of them, it's hard to know what was exactly the cause of the problem.

Now I'm happy

Answer 5

My problem was the first issue described here:

"First, you need to make sure your app-id in the Portal is correct."

Answer 6

It seems people are getting confused on Product IDs.

You DON'T need to add the whole domain (ex. com.company.product.inappname) for InApp to work.

You MUST use the EXACT Product ID you create on iTunes Connect. In my case, I just created "Product1", used this when SKProductsRequest is called and that's it.

No more pain.
